About These Blogs: The JPL Science & Technology Blogs are a way for our researchers and technical staff to give first-hand accounts of the activities that are going on at the Jet Propulsion Laboratory. A cross-section of our staff contribute posts about the tasks they are currently involved in for NASA and JPL. These blog posts are meant to discuss technical topics. Selected comments that are on-topic are published and are moderated.

The Microwave Limb Sounder (MLS) on NASA’s Aura satellite measures a suite of atmospheric gases, temperature and cloud ice in the limb view of Earth’s atmosphere from microwave thermal emissions. I use mainly the MLS water vapor and cloud ice products to study climate variabilities. Some of my colleagues in the MLS group make use of MLS products, such as carbon monoxide (CO), ozone (O3), nitrous oxide (N2O), chlorine monoxide (CLO), nitric acid (HNO3), HCL, and HCN, etc, to study atmospheric tracer ...
